Pantsless, eh? Sounds not good on a few levels, and I'm not even gonna go check out Prolly's link--doesn't sound safe for work (or heterosexuality, either!)! ;o)

Though, a number of years back, I was grinding up a mountain trail when I noticed a biker on the way down. As we passed--me ascending, he descending--I noticed that he was doing so sans pantalones! Fortunately, for safety's sake, he was wearing gloves, helmet and shoes.

Anywho, reconsider the pantslessness option as road rash would not do you well!
